With Vegas especially, I recommend checking all the Harrah's properties individually via hot Deals rates for the most standard rooms. Avoid Imperial Palace. Consider the Rio, which though off-central Strip, has great rooms and a free continuous Strip shuttle (5 mins to Caesars) if you dont want to deal with the parking garage hassles -- and is closer to center Strip than Luxor/Mandalay Bay. The MGM properties (Luxor, TI, Mirage, Monte Carlo etc) have promos on their websites. I'd also use a secondary email to sign up for each casino hotel's emails/deals, i.e. TI just had a great deal valid for 72 hours only (ended on Thursday) that would've applied to your stay. For your dates, I would also strongly recommend booking a cancellable back-up. Typically you get charged the 1st night rate as a refundable deposit, and it locks in the rate in case your PL bidding isn't successful. For example the hot Deal rate for Flamingo is $110 for 24th and $85 for 25th, which would put you under the $100/night threshhold. Yes, i know it's not a 4-star or in the $60 range. But it is too risky to bid 3-star North Strip because of Imperial Palace, Riviera, Strat etc. (one of those aforementioned properties is showing at $45/night on HOTWIRE)....and 3-star Strip South could get you the Trop or Excalibur or a Luxor upgrade. Also dont forget to be creative and look at all options. For example, Hilton Grand Vacations (Hilton-owned and also used as a timeshare with more weekend demand) is coming up at a $98 pre-paid (nonrefundable) rate and $109 normal rate (I believe you could knock the $109 to $98 if a AAA member). Friend stayed there once, beautiful property, pool, kitchenette, view, no casino/smoke, very impressive albeit small room. It is North Strip though but if I had a chance at that rate, I wouldn't think twice. It's not 4-star per se based on no fullservice restaurant/entertainment amenities. I'm not so much recommending this place specififcally, just using it as a good example of what may be out there if you do your homework. Good luck.
